At Joyent we have long had a focus on high performance, whether it's through innovations in SmartOS, carefully selecting our hardware, or providing customers with tools such as DTrace to identify bottlenecks in their application stacks.

Recently, Joyent published a series of benchmarks using YCSB (Yahoo Cloud Service Benchmark)
comparing the performance of MongoDB, PostgreSQL, and Elasticsearch between machines running
in the Joyent Public Cloud and similarly configured machines running on Amazon Web Services.

We would like to share the details on what occurred during the outage on 5/27/2014 in our us-east-1 datacenter, what we have learned, and what actions we are taking to prevent this from happening again.
